Evaluation of Ultrasound Screening Method and Prevalence for Developmental Hip Dysplasia In The Central Anatolia

Objectives:This study aimed to assess the frequency and subsequent results of developmental dysplasia of the hip (DDH) in newborns in Central Anatolia who were admitted to Konya City Hospital and evaluate the efficiency of the existing screening and treatment methods in detecting and managing DDH in infants. Methods: Total of 10,650 infants were evaluated who had Graf USG screening in Konya City Hospital. İnfants born at or after 38 weeks of gestation were included, while premature infants were excluded. Additionally, we included infants who underwent USG screening between 30 and 90 days after birth, and whose hip development physiology was adequately visualized and assessed during the USG examination. Results: The study examined 8,695 term infants (52.5% male, 47.5% female) who underwent USG screening between 2020 and 2022. Participants mean gestational age at the time of the first USG examination was 7.94±2.07 weeks. Graf type 1 was higher in males (%97-96,5) and graf type 2 was higher in females (%7,2-7,8). Radiologists prefer to re-examine after 1 month for type 2a(%84,49-82,02) but orthopaedic consultation for type Type-2B, 2C, and type-3. The majority of infants (93.6%) underwent only one USG screening. No patients who continued regular USG control and treatment required surgical treatment requiring osteotomy. Conclusion: USG is an early diagnostic method for developmental hip dysplasia (DDH), which allows for simple treatment options and prevention of complications. It is a simple, inexpensive, and non-invasive method. Our study supports that regular USG screenings in infants eliminate the need for surgical procedures requiring osteotomy.
